The Q70A and Q80A are the 2021, the seventh and eighth series of QLED TVs. In this article, I will tell you what the differences are between these two TV models.

Differences between Q80A vs Q70A

Now about the differences between these TV models. TVs differ in the screens, this is the main difference which affects the image quality. Q70A because this TV is lower class is equipped with a screen manufactured with EDGE backlighting. TV Q80A is equipped with a screen manufactured with direct backlighting. This allows you to more fully use the technology screen dimming zones.

The second significant difference Q80A equipped with acoustics 2.2.2CH, it is 6 speakers, 4 speakers for sound and two subwoofers, a total power of 60W. The Q70A model has only two speakers with 20W power.

Note that all other parameters of TVs Q80A and Q70A are the same.

Which TV to buy Q80A or Q70A?

Given the fairly small price difference, of course it is more preferable to buy a Q80A series TV. You will end up with a higher quality picture.

  1. Great comparison between the Samsung Q70A and Q80A! It’s helpful to know that the Q80A offers better picture quality, sound, and smart features compared to the Q70A. This information will definitely help me make an informed decision when choosing a new TV for my home entertainment system. Thanks for sharing!

      VA or ADS Visually, it’s easy to tell.
      ADS is an IPS screen matrix technology.
      Look at the image by moving from the center of the screen up and down, if the image contrast changes (usually increases when viewed from above, decreases when viewed from below), then it is a VA matrix, if the image does not lose contrast (remains unchanged), then it is a TV with an ADS screen.
